Hi David,
Each filter is designed to filter a certain volume of oil and
sizes are determined by engine capacity and horsepower. Single filters use 1
filter roll, doubles use 2, and trebles use 3. The filter roll is contained
and restrained in a can, which slides onto a shaft pipe, sealed top and
bottom with a nitrile rubber seal, with each can being separated from one
another by something like 5/8'. The only way out for the oil is through the
filter, back up through a central shaft complete with top flange (boss) that
is fitted into the core to the top of each filter roll height and then out
through the shaft pipe. Each filter roll filters a certain volume of oil
independently thus maximising the volume of oil that each filter can handle
unlike what would happen if each filter roll was stacked on top of one
another and all the oil had to go from one end to the other ( possibly what
you have visualised and the reason for your question). Hope this explains
it.
B.r., David
